Description

Technical Field

[0001] The utility model relates to the technical field of lamps, and in particular to an LED lamp and a lighting system provided with the LED lamp. Background Art

[0002] In order for a ceiling lamp to present a good light spot effect, it depends largely on the design of the light source board. The existing ceiling lamps basically use a single fixing method to fix the lamp holder and the light source board. For example, multiple through holes are set on the substrate of the light source board, and multiple connection holes matching the multiple through holes are injection molded on the lamp holder. When the lamp holder and the light source board are assembled, bolts are passed through the through holes and then threadedly connected with the corresponding connection holes; however, this fixing method has the following shortcomings: high requirements on the material properties of the lamp holder, and it is easy to have problems such as slipping and bursting of the connection holes when installing the bolts. At the same time, the installation of the bolts increases the complexity of assembly, making the assembly efficiency of the ceiling lamp low, which leads to high production costs.

[0003] In order to solve the shortcomings of the above-mentioned ceiling lamps, the lamp holders of some existing ceiling lamps will change the design of the connecting holes into hot melt columns, so that when the lamp holder and the light source board are assembled, each hot melt column is inserted into a through hole corresponding to it on the base plate, and then a plurality of hot melt columns are simultaneously hot-melted by hot melt equipment, so that the hot-melt columns after hot-melting can fasten the light source board to the lamp holder. Since no bolts are required when the lamp holder and the light source board are assembled, the assembly efficiency can be greatly improved and the production cost can be reduced. However, these ceiling lamps still use a single fixing method, which may cause the light source board to be disconnected from the lamp holder due to failure of a single structure (such as cracking or breaking of the hot-melt deformed part of the hot melt column) during transportation or user use, thereby affecting the use of the ceiling lamp. Summary of the invention

[0004] In order to solve the above problems, the main purpose of the utility model is to provide an LED lamp that is easy to install and has good fixing firmness.

[0005] Another object of the utility model is to provide a lighting system equipped with the above-mentioned LED lamp.

[0006] In order to achieve the main purpose of the utility model, the utility model provides an LED lamp, including a light source board and a lamp holder, the light source board includes a substrate and multiple LED lamp beads, the substrate is provided with multiple through holes penetrating the substrate, the multiple LED lamp beads are installed on the substrate, the lamp holder has a accommodating cavity, the bottom wall of the accommodating cavity is formed with multiple hot melt columns, the multiple hot melt columns correspond one-to-one to the multiple through holes, and one hot melt column is inserted into a corresponding through hole, wherein the substrate is also provided with multiple card slots penetrating the substrate, and the bottom wall is formed with an elastic buckle at each card slot, and the elastic buckle is engaged and connected with a corresponding card slot.

[0007] As can be seen from the above, by setting a card slot on the substrate and setting an elastic clip matching the card slot on the lamp holder, the card slot and the elastic clip can cooperate with the through hole on the substrate and the hot melt column on the lamp holder to compositely fix the light source board and the lamp holder, thereby better preventing the light source board from being disconnected from the lamp holder during transportation or user use, thereby improving the reliability of the LED lamp.

[0008] A preferred solution is that the elastic buckle has a gantry and an elastic claw, the elastic claw has an elastic arm portion and a claw portion, the elastic arm portion is located in the gantry, the elastic arm portion extends from the top of the gantry to the bottom of the gantry, the claw portion protrudes from the extended end of the elastic arm portion to the outside of the gantry in the width direction of the gantry, there is a gap between the claw portion and the bottom wall, and the base plate is located in the gap.

[0009] As can be seen from the above, through the design of the elastic clip, the strength of the elastic clip is guaranteed, making the elastic clip not easily broken or damaged during the assembly process with the slot of the substrate, and at the same time, a large gap between the elastic clip and the slot after assembly can be avoided, thereby ensuring the stability of the elastic clip and the slot after assembly, and also facilitating the resetting of the elastic claws of the elastic clip and buckling them on the substrate.

[0010] A further solution is that a first width of the bottom of the gantry is less than or equal to the second width of the slot, a first guide slope is formed on the side of the gantry protruding away from the claw, and a fourth width of the top of the gantry is less than the first width of the bottom of the gantry; a second guide slope is formed on the claw, and the substrate can force the elastic claw to elastically deform toward the first guide slope through the second guide slope.

[0011] As can be seen from the above, the setting of the first guiding bevel is conducive to the insertion of the gantry into the card slot of the substrate, and guides the substrate during the insertion process; the design of the second guiding bevel is conducive to the substrate pushing the elastic claw to deform so as to better pass over the claw portion of the elastic claw, and after the substrate passes over the claw portion, the claw portion is buckled on the substrate under the action of the elastic arm portion.

[0012] Another preferred solution is that the hot melt column is in a frustum-like shape before being hot melted.

[0013] As can be seen from the above, this design facilitates the hot melt column to be inserted into the through hole of the substrate.

[0014] A further solution is that the cross section of the hot melt column before being hot melted is cross-shaped or star-shaped.

[0015] As can be seen from the above, this design further facilitates the hot melt column to be inserted into the through hole of the substrate, and enables the hot melt column after heat melting to better fill the through hole and fix the substrate on the lamp holder.

[0018] A further solution is that an indication mark is also arranged on the bottom wall.

[0019] As can be seen from the above, the design of indicator marks is conducive to the rapid positioning of the lamp holder and the light source board, thereby helping to improve assembly efficiency.

[0020] A further solution is that the bottom wall is also provided with a positioning anti-foolproofing slot, which is engaged and connected with the protruding end of the circular plate portion.

[0032] LED lamp embodiment

[0033] Reference Figure 1 The LED lamp 100 includes a light source board 1, a lamp holder 2 and a lampshade (not shown). The lamp holder 2 has a receiving cavity 21, the light source board 1 is mounted on the bottom of the receiving cavity 21, the lampshade is connected to the lamp holder 2, and the lampshade covers the opening of the receiving cavity 21. Preferably, the lampshade is made of PMMA (polymethyl methacrylate) material, so that the lampshade has good light transmittance, thereby ensuring the lighting effect of the LED lamp 100.

[0034] Combination Figure 2 and Figure 3 The light source board 1 includes a substrate 11 and a plurality of LED lamp beads 12. The substrate 11 is provided with a plurality of through holes 111 and a plurality of slots 112 that penetrate the substrate 11; the plurality of LED lamp beads 12 are mounted on the substrate 11 and are electrically connected to the substrate 11. A plurality of hot melt columns 22 are formed on the bottom wall of the accommodating cavity 21 of the lamp holder 2, and the plurality of hot melt columns 22 correspond one-to-one to the plurality of through holes 111 on the substrate 11, so that when the light source board 1 is assembled on the lamp holder 2, one hot melt column 22 is inserted into a corresponding through hole 111; in addition, an elastic buckle 23 is formed at each slot 112 on the bottom wall of the accommodating cavity 21, and the plurality of elastic buckles 23 correspond one-to-one to the plurality of slots 112 on the substrate 11, so that when the light source board 1 is assembled on the lamp holder 2, one elastic buckle 23 is inserted into a slot 112 and is engaged with the slot 112, thereby fixing the light source board 1 on the lamp holder 2.

[0035] Preferably, the substrate 11 has a mounting plate portion 113 and a circular plate portion 114. The mounting plate portion 113 is preferably integrated with a driving unit 1131, so that the LED lamp 100 does not need to be additionally provided with a driving unit 1131, and does not need to form a structure connected to the driving unit 1131 on the lamp holder 2, so as to better simplify the structure of the lamp holder 2 and reduce the production cost; the circular plate portion 114 extends from the mounting plate portion 113 and extends in a circular shape around the mounting plate portion 113, and the plurality of LED lamp beads 12 are all mounted on the circular plate portion 114 and distributed along the extension direction of the circular plate portion 114, and the plurality of LED lamp beads 12 are all electrically connected to the driving unit 1131, so that the driving unit 1131 can drive the plurality of LED lamp beads 12 to emit light according to the set mode, and the design of the circular plate portion 114 is conducive to the light source to better cover the lamp holder 2, thereby ensuring the lighting effect of the LED lamp 100. In addition, at least one through hole 111 and at least one card slot 112 are distributed on the mounting plate portion 113, and a plurality of through holes 111 and a plurality of card slots 112 are provided on the circular plate portion 114. The plurality of through holes 111 are distributed along the extension direction of the circular plate portion 114, and the plurality of card slots 112 are distributed along the extension direction of the circular plate portion 114. It should be noted that there are no special requirements for the relative positions of the through holes 111 and the card slots 112 on the mounting plate portion 113 and the circular plate portion 114, and they can be used to fix the light source panel 1 and the lamp holder 2.

[0036] Combination Figure 4 , the hot melt column 22 is preferably in a quasi-cone shape (such as a truncated cone or a prism shape) before being hot-melted, so as to be more conducive to the hot melt column 22 being inserted into the through hole 111 of the substrate 11 when the light source board 1 and the lamp holder 2 are assembled. Preferably, as in the present embodiment, the cross section of the hot melt column 22 before being hot-melted is in a cross shape, which further facilitates the hot melt column 22 to be inserted into the through hole 111 of the substrate 11 (reducing the friction between the hot melt column 22 and the through hole 111 during assembly), and can make the hot melt column 22 after hot-melting better fill the through hole 111 and fix the substrate 11 on the lamp holder 2; of course, in other embodiments, the cross section of the hot melt column 22 before being hot-melted may also be in a quasi-star shape.

[0037] Combination Figure 5 The elastic buckle 23 on the lamp holder 2 preferably has a gantry 231 and an elastic claw 232. The first length L1 of the gantry 231 is less than or equal to the second length L2 of the slot 112, and the first width W1 of the bottom of the gantry 231 (the maximum width of the gantry 231) is less than or equal to the second width W2 of the slot 112; preferably, the first length L1 is slightly less than the second length L2, and the first width W1 is slightly less than the second width W2, so that the elastic buckle 23 is easier to insert into the slot 112 on the substrate 11, and the friction force of the elastic buckle 23 during the insertion into the slot 112 is reduced.

[0038] The elastic claw 232 has an elastic arm portion 2321 and a claw portion 2322; the elastic arm portion 2321 is located inside the gantry 231, and the elastic arm portion 2321 extends from the top of the gantry 231 to the bottom of the gantry 231; the claw portion 2322 protrudes from the extended end of the elastic arm portion 2321 to the outside of the gantry 231 in the width direction of the gantry 231, wherein the third width W3 of the claw portion 2322 is less than or equal to the second width W2 of the card slot 112, preferably, the third width W3 is less than the second width W2, so that the card slot 112 can smoothly pass over the claw portion 2322. In addition, there is a gap between the claw portion 2322 and the bottom wall of the accommodating cavity 21, and when the light source board 1 is assembled and the lamp holder 2 is mounted, the substrate 11 is located in the gap, and preferably the substrate 11 can just be adjacent to the bottom wall of the accommodating cavity 21 and the claw portion 2322.

[0039] Through the design of the elastic buckle 23, the strength of the elastic buckle 23 can be ensured, so that the elastic buckle 23 is not easily broken or damaged during the assembly process with the slot 112 of the substrate 11, and a large gap between the elastic buckle 23 and the slot 112 after assembly can be avoided, thereby ensuring the stability of the elastic buckle 23 and the slot 112 after assembly, and also facilitating the elastic claw 232 of the elastic buckle 23 to reset and buckle on the substrate 11. Preferably, a first guiding bevel 2311 is formed on the side of the gantry 231 protruding away from the claw portion 2322, so that the fourth width W4 of the top of the gantry 231 is smaller than the first width W1 of the bottom of the gantry 231. The first guiding bevel 2311 enables the gantry 231 to be better inserted into the slot 112 of the substrate 11, and guides the substrate 11 during the insertion process; the claw portion 2322 is formed with a second guiding bevel 23221, so that when the light source board 1 and the lamp holder 2 are assembled, the substrate 11 can force the elastic claw 232 to elastically deform toward the first guiding bevel 2311 through the second guiding bevel 23221. It can be seen that the setting of the second guiding bevel 23221 is beneficial to the substrate 11 to push the elastic claw 232 to deform so as to better pass over the claw portion 2322 of the elastic claw 232, and after the substrate 11 passes over the claw portion 2322, the claw portion 2322 is buckled on the substrate 11 under the action of the elastic arm portion 2321.

[0040] Furthermore, the base is also provided with an indication mark on the bottom wall of the accommodating cavity 21, so as to facilitate the quick identification and positioning of the assembly position of the lamp holder 2 and the light source board 1, thereby facilitating the improvement of the assembly efficiency. Furthermore, the base is also provided with a positioning anti-fool card slot 25 on the bottom wall of the accommodating cavity 21, and the positioning anti-fool card slot 25 is used to engage with the extended end of the circular plate portion 114 to better prevent errors in the assembly of the light source board 1, thereby further improving the assembly efficiency in conjunction with the indication mark 24.

[0041] Furthermore, the substrate 11 is an aluminum substrate, a ceramic substrate or a composite substrate (MCPCB, metal-based printed circuit board) to ensure the heat dissipation performance of the LED lamp beads 12, so that the LED lamp beads 12 can work stably and extend the service life of the LED lamp beads 12. In addition, the lamp holder 2 is preferably made of a material with high thermal conductivity such as ABS (acrylonitrile-butadiene-styrene copolymer) material, PVC (polyvinyl chloride plastic) material, PP (polypropylene) material, PBT (polybutylene terephthalate) material or PC (polycarbonate) material, so that the lamp holder can reliably dissipate heat for the light source board 1 to ensure the stability and service life of the light source board 1.

[0042] In summary, it can be seen that the matching connection between the through hole 111 on the substrate 11 and the hot melt column 22 on the lamp holder 2, combined with the matching connection between the card slot 112 on the substrate 11 and the elastic buckle 23 on the lamp holder 2, can realize the composite fixation of the light source board 1 and the lamp holder 2, thereby better preventing the light source board 1 from being separated from the connection with the lamp holder 2 during transportation or user use of the LED lamp 100, thereby improving the reliability of the LED lamp 100; in addition, when the hot melt equipment presses the light source board 1 into the lamp holder 2 so that the hot melt column 22 on the lamp holder 2 is inserted into the corresponding through hole 111 on the substrate 11, the elastic buckle 23 on the lamp holder 2 can be synchronously inserted into the card slot 112 on the substrate 11 to engage with the card slot 112, thereby realizing the simultaneous assembly of the hot melt connection and the buckle connection, without the need for additional processes, thereby ensuring the convenience and efficiency of assembly.
